CVE-2019-17185: Freeradius

High severity, CVSS 7.5. EPSS: 2.2% chance of exploitation in the next 30 days.

In FreeRADIUS 3.0.x before 3.0.20, the EAP-pwd module used a global OpenSSL BN_CTX instance to handle all handshakes. This mean multiple threads use the same BN_CTX instance concurrently, resulting in crashes when concurrent EAP-pwd handshakes are initiated. This can be abused by an adversary as a Denial-of-Service (DoS) attack.

Affected products

• Freeradius Freeradius: from 3.0.0, before 3.0.20 (fixed in 3.0.20)
• Opensuse Leap: version 15.1 only
